PRECAUTIONS
PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
AKS00B9V
A
The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used al ong
with a front seat belt, helps to redu ce th e risk or se verit y of i njury to the driv er and front passenge r for ce rtain
types of col lision. Information necessary to service the system safely is includ ed in the SRS a nd SB section of
this Service Manual.
WARNING:
● To avoid rendering the SRS inopera tive, whi ch could incr ease the risk of pe rsonal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
● Improper maintenance, inc luding incorrect removal and installation of the SRS, can lead to per-
sonal injury ca use d by unintentional ac tiv atio n o f the s ys t em . F or re mo va l of Spiral Cable and Ai r
Bag Module, see the SRS sec tion.
● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Wiring Diagrams and Trouble Diagnosis AKS00B9W
When reading wiring diagrams, refer to the following:
● GI-14, "How to Read Wiring Diagrams" in GI section
● PG-2, "POWER SUPPLY ROUTING" for power distribution circuit in PG section
When performing trouble diagnosis, refer to the following:
● GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section

COMBINATION METERS
COMBINATION METERS PFP:24814 System Description AKS00B9X
UNIFIED METER CONTROL UNIT
● Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter.
● Digital meter is adopted for odo/trip meter*.
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
● Meter/gauge and odo/trip meter segments can be checked in diagnosis mode.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all time s
● through 10 A fuse [No. 28, located in the fuse block (J/B)]
● to combination meter terminal 1.
With the ignition switch in the ON or START position, power is supplied
● through 10 A fuse [No. 11, located in the fuse block (J/B)]
● to combination meter terminal 2.
Ground is supplied
● to combination meter terminal 21
● through grounds M27 and M70.
ODO/TRIP METER, CLOCK AND AMBIENT TEMPERATURE INDICATOR
● The vehicle speed s ignal and the memory sig nals from the meter memory c ircuit are processed by t he
combination meter and the mileage is displayed.
● Ambient temperature indicator indicates signal from ambient sensor processed by the combination meter.
How to Change The Display
Depressing the odo/trip meter switch toggles the mode in the following order.
SKIA8917E
● The odo/tr ip mete r displ a y mo de togg li ng an d tr ip di spla y r es ett i ng can be ide nt i fie d b y th e a mo unt o f t ime
that elapses from pressing the odo/trip meter switch to releasing it.
● When resetting with trip A displayed, only trip A display is reset. (The same way for trip B.)
SPEEDOMETER
VDC/TCS/ABS control unit [with VDC] or ABS actuator and electric unit (control unit) [without VDC] provides a
vehicle speed signal to the combination meter for the speedometer with CAN communication line.

COMBINATION METERS
TACHOMETER
The tachometer indicates engine speed in revol uti on s pe r minu te (rpm).
ECM provides an engine speed signal to combination meter for tachometer with CAN communicati on line.
A
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to combination meter for water temperature gauge with
CAN communication line.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
● from grounds M2 7 an d M70
● through terminals 1 and 4 of the fuel level sensor unit
● through terminals 3 and 1 of the sub fuel level sensor unit and
● to combination meter terminal 8 for the fuel gauge.
AMBIENT TEMPERATURE INDICATOR
The ambient temperature is indicated by the signal from ambient sensor.
Combination meter inputs voltage conversed from resistance which ambient sensor detects.
Indication range is between -30 an d 5 5 °C (-22 a nd 13 1 °F). When ambient temperature is less than -30 °C (22 °F) or more than 55 °C (13 1 °F ), di splay shows “--- °C”. When in dica ted te mpera tu re bec omes less tha n 3
°C (37 °F), ambient temperature indicator flashes as a sign of warning.
Without Auto A/C
Power is supplied
● through combination meter terminal 27
● to ambient sensor terminal 1.
Ground is supplied
● to combination meter terminal 28
● through ambient sensor terminal 2.
Signal is supplied
● through ambient sensor terminal 1
● to combination meter terminal 27.

● to combination meter terminal 27.
NOTE:
Combination m eter distinguishes whet her or not combinatio n meter terminal 29 rece ives voltage (Auto A/C
recognition signal) from A/C auto amp. terminal 28. If the terminal receives, combination meter discerns as
auto A/C.
Indication When Turning Ignition Switch OFF

CAN Communication AKS00BQ7
SYSTEM DESCRIPTION
CAN (Controller Area N et w ork ) is a s eri al co mm u nic a tio n l ine for real time appl ic ati on . It is an on-vehicle multiplex communi catio n lin e wit h high da t a comm unic ation speed and ex cellen t er ror det ecti on ab ilit y. Many electronic control u nits are eq uipped o nto a ve hicle, a nd eac h control unit sh ares info rmation and link s with ot her
control units duri ng operation (not independent). In CAN communicatio n, control units ar e connected wi th 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN COMMUNICATION UNIT
Refer to LAN-16, "CAN Communication Unit" in “LAN SYSTEM”.
